In the figure above, lines lll and mmm are parallel and lines sss and ttt are parallel. If the measure of ∠1\angle1∠1 is 65°65\degree65°, what is the measure of ∠2?\angle2?∠2?
When two parallel lines are cut by a transversal, we generally obtain the following properties:
In our case, there are 2 sets of 8 equivalent angles.
